Question

您好我为RTS游戏创建了一个相机我正在制作但是在开始时相机处于minHight位置并且我无法弄清楚如何更改它希望有人帮助代码有点混乱它只是为了测试这里是我希望它从给出的maxHight位置开始而不是在minHight上的代码。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RtsCamera : MonoBehaviour {


    public float zoomSensitivy = 15;
    private Transform m_Transform;
    public float screenEdgeBorder = 25f;
    public bool useScreenEdgeInput = true;
    public float screenEdgeMovementSpeed = 3f;

    // zoom stuff
    public float heightDampening = 5f;
    public float scrollWheelZoomingSensitivity = 25f;
    public float maxHeight = 10f; //maximal height
    public float minHeight = 15f; //minimnal height
    public LayerMask groundMask = -1;
    public bool autoHeight = true;
    public bool limitMap = true;
    public float limitX = 50f; //x limit of map
    public float limitZ = 50f; //z limit of map
    private float zoomPos = 0; //value in range (0, 1) used as t in Matf.Lerp
    public bool useScrollwheelZooming = true;

    Vector3 tempPos;


    public string zoomingAxis = "Mouse ScrollWheel";

    private float ScrollWheel
    {
        get { return Input.GetAxis(zoomingAxis); }
    }

    private Vector2 MouseAxis
    {
        get { return new Vector2(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y")); }
    }
    private Vector2 MouseInput
    {
        get { return Input.mousePosition; }
    }


    private void Start()
    {

        m_Transform = transform;

    }
    // Update is called once per frame
    void Update () {
        Move();
        LimitPosition();
        HeightCalculation();







    }
    private void Move()
    {


        if (useScreenEdgeInput)
        {
            Vector3 desiredMove = new Vector3();

            Rect leftRect = new Rect(0, 0, screenEdgeBorder, Screen.height);
            Rect rightRect = new Rect(Screen.width - screenEdgeBorder, 0, screenEdgeBorder, Screen.height);
            Rect upRect = new Rect(0, Screen.height - screenEdgeBorder, Screen.width, screenEdgeBorder);
            Rect downRect = new Rect(0, 0, Screen.width, screenEdgeBorder);

            desiredMove.x = leftRect.Contains(MouseInput) ? -1 : rightRect.Contains(MouseInput) ? 1 : 0;
            desiredMove.z = upRect.Contains(MouseInput) ? 1 : downRect.Contains(MouseInput) ? -1 : 0;

            desiredMove *= screenEdgeMovementSpeed;
            desiredMove *= Time.deltaTime;
            desiredMove = Quaternion.Euler(new Vector3(0f, transform.eulerAngles.y, 0f)) * desiredMove;
            desiredMove = m_Transform.InverseTransformDirection(desiredMove);

            m_Transform.Translate(desiredMove, Space.Self);
        }

    }
    private void LimitPosition()
    {
        if (!limitMap)
            return;

        m_Transform.position = new Vector3(Mathf.Clamp(m_Transform.position.x, -limitX, limitX),
            m_Transform.position.y,
            Mathf.Clamp(m_Transform.position.z, -limitZ, limitZ));
    }

    private void HeightCalculation()
    {
        float distanceToGround = DistanceToGround();
        if (useScrollwheelZooming)
            zoomPos += ScrollWheel * Time.deltaTime * scrollWheelZoomingSensitivity;


        zoomPos = Mathf.Clamp01(zoomPos);

        float targetHeight = Mathf.Lerp(minHeight, maxHeight, zoomPos);
        float difference = 0;

        if (distanceToGround != targetHeight)
            difference = targetHeight - distanceToGround;

       m_Transform.position = Vector3.Lerp(m_Transform.position,
            new Vector3(m_Transform.position.x, targetHeight + difference, m_Transform.position.z), Time.deltaTime * heightDampening);
    }
    private float DistanceToGround()
    {
        Ray ray = new Ray(m_Transform.position, Vector3.down);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit, groundMask.value))
            return (hit.point - m_Transform.position).magnitude;

        return 0f;
    }



}

将第25行的变量zoomPos的值设置为1或0，具体取决于您是希望它在最小高度还是最大高度，您可以在Start()或只是在变量的声明。

这是因为在HeightCalculation函数中，它根据zoomPos的值将高度设置在最小值和最大值之间，当您使用滚轮时，此值会更改，缩放也会更改。在运行游戏之前更改zoomPos可以有效地设置默认的起始高度。
